FRONT MOTOR MOUNTING.

Application filed January 8, 1927. Serial No. 159,865.

This invention relates to motor vehiclesl and more particularly to anrimproved form of mounting, for suspending the front of the engine on thechassis frame.

5 In the customary three point. engine suspension 'arrangement forautomobiles, it is desirable that the central front suspension point belocated at the front of the engine cylinder block. In an automobile of awell 10 known manufacturer, the mounting has heretofore been such thatthe motor was supported thru the lower half of the front main bearingfor the crankshaft. In order to replace the bearing, it has beennecessary to remove and raise the motor from the front support, topermit access to the bearing.

One of the objects of the present invention is to provide a. singlepoint mounting for the front of the engine, which is independent of thefront bea-ring, and will permit removal of the bearing with themotorsccured in position and without disturbing` the mounting.

Other objects will he apparent from the following specification and theaccompanying drawing, wherein Figure 1 is a. front elevation, partlybroken away, of the support between the front of the engine and chassisframe; Figure 2 is a side elevation, partly in section, of the frontengine mounting; und Figure 3 is a detail view illustrating the removalof the bearing cap.

Referring to the drawing, which shows a referred, but not necessarilythe only embodiment of the invention, the reference character 1,indicates the front of the engine cylinder block, 2 the housing for thecam shaft d rive, and the driving pulley on the engine crankshaft, forthe usual radiator fan. 'Ihe front main bearing for the crankshaft iconsists of the upper and lower halves 5 and 6, and the bearing cap 7,held to the under side of the front end of the cylinder block by boltsS. A felt washer 9 between the bearing cap 'i' and oil pan 10, providesa seal to prevent lea Tage of crankcase oil.

Any suitable form of supports may be provided for the rear of the motor,and since such supports do not constitute al part of the presentinvention, they have not been illustrated.

In order to mount the front of the engine at a single point, and at thecenter thereof,

but independent of the main bearing, there is provided a U-shapedbracket or chair member-11, which straddles or overlies the bearingcap-7. The opposite ends of the U-shaped bracket are turned outwardlyand secured to the underside of the cylinder block, beyond the bearingcap, by the belts 1,2-12, while the lcross portion connecting theupsta'nding side arms, is secured by the single bolt 13, to thetransverse cross bar 14 of the chassis frame. In this instance, thecross bar 14 extends forwardly and upwardly, above the front axle 15 andaffords a support for the radiator 16.

From the above description, it will be apparent that upon removal of theoil pan 10, the bolts S may be unthreaded from the cylinder block, andas clearly shown in Figure 3. the intermediate space afforded by theU-shaped bracket is sufficient to permit ready removal of the bearingcap 7, without disturbing` the mounting, which in addition to effectinga` saving of time for the repairman, also serves to eliminate thepossibility of his failure to properly remount the engine in properposition.

lVhile the invention has been described more or less specifically it isto be understood, that the invention is not limited to the exactdetails, but that such obvious modifications may be made as come. withinthe scope of the appended claims.

Having described my invention, I claim:

1. In a motor vehicle, the combination ef .an engine, a chassis framemember extending transversely of the engine, and means to support thefront ond of the engine upon said frame member, including a member`connecting the engine and frame and adapted to overlie the front maincrankshaft bearing of the engine and arranged for the ready removal ofthe bearing without disturbing said supporting means.

2. In a motor vehicle. the combination of an engine, a frame member anda connection therebetween, including a bracket having au intermediatespace which. is adapted to overlie the front main crankshaft bearing ofthe engine, while permitting access thereto.

3. In a motor vehicle, the combination of a motor, a supporting frametherefor, means to mount one end of the motor, centrally thereof to saidframe, including a. U-shaped bracket, adapted to straddle the front maincrankshaft bearing, the opposite ends of the U-braeket being secured tothe engine at points beyond the bearingcap7 and the cross portion of thebracket being secured to the frame, `the intermediate space afforded bythe U-shaped bracket being' such as to permit removal of the bearing'cap Without disturbing` the engine mounting.

4. In a motor vehicle, the combination of an engine block, a bearing capbearing, a chassis frame member extending transversely of the engine anda bracket connecting the front of the engine to the frame member, saidbracket having' a space which is adapted to straddle'tho bearing cap andpermit'i'e- `moval thereof. without disturbing the connection betweenthe engine block and frame member. Y l v 5. In a` motor vehicle, thecombination of a chassis frame member, an engine slipported thereon,having a removable shaft bearing overlying the frame member, and meansor connecting` the engine with the frame member adjacent said' bearing,but independently thereof, the parts'b'eingarranged to permit access tothe bearing Without disconnectingv 'the engine from the frame.

6. In a motor vehicle, the combination of a chassis frame member. anengine to be supported thereon, means vfor connecting lthe engine andframe memberg and a removable engine shaft bearing overlying said framemember and accessible for removal independently of the Saidconnectingnieans.-
